Guidelines for Evaluation and Improvement of Reuse and Experience Repository Systems through Measurement Programs

Software development organizations are recognizing the increasing importance of investing in the build-up of core competencies for their competitiveness in software system development. This is supported by reuse and experience repository systems that assist in capturing and reusing all kinds of software artifacts (e. g., code, patterns, frameworks) and processes as well as experiences related to these artifacts and processes. To justify such an investment and guide its improvement, it must be evaluated according to the business case, that is, a measurement program has to be developed that is oriented towards the business goals of such a reuse and experience repository system. In this paper, we suggest an approach to iteratively build up measurement programs for gaining feedback and, thereby, controlling and improving such a reuse and experience repository system. The focus is placed on guidelines for the evolution of such measurement programs over time, rather than providing directly applicable metrics or questionnaires. In order to illustrate the feasibility of the approach, examples of running measurement programs at different stages of evolutions are given.
